104,545 of the 965,200 top sites in our Tranco top-1M census run Microsoft 365 (10.8%). Microsoft's subscription suite of productivity apps and services, including Exchange Online email hosting. Detection is homepage-level HTML/header fingerprinting, so a site can run Microsoft 365 on other pages without it showing here.
